Description

ISC reports :

Parsing a malformed DNSSEC key can cause a validating resolver to exit due to a failed assertion in buffer.c. It is possible for a remote attacker to deliberately trigger this condition, for example by using a query which requires a response from a zone containing a deliberately malformed key.
